Bill of Materials:- plywood: TBD, scraps could do if you can make segmented turnings, outer shell can be a pyramid or a cone- motor: $10- power supply unit: $10- Lazy Susan bearings: $4.50 plus postage (or get them at your local DYI store)- misc electric stuff: depending on the command mode. If RC, add around $20.- add the cord of course :)

so far, for the motorized function, we’re around $40 give or take.

Time wise, I’ll have to actually build it to be able to give a decent value, but this part will depend on the technique chosen for the cylinders (bent lamination of cheap veneer, segmented plywood turning, or even a mere octagon or other high facet count thing).

Now to end packing up for the 10 hour road trip tomorrow… TTYL
